    摘要: Active material actuator assemblies are provided that enable simplified control systems and faster actuator cycle times. A movable member is provided that has multiple active material components operatively connected to it. The active material components are separately selectively activatable for moving the movable member. Movement of the movable member via activation of a first of the active material components triggers activation of the second active material component to further move the movable member. Alternatively or in addition, previously activated active material components are protected from undesired stretching during activation of another active material component or, when desired, an active material component may be reset via activation of another of the active material components in order to prepare it for subsequent activation.

    摘要: A seal assembly configured for sealing a dynamic shaft includes an elastic seal member disposable in sealing communication with the dynamic shaft. The seal assembly further includes a coil spring and a shape memory alloy element. The coil spring is disposed in contact with the elastic seal member and configured for applying a compressive force to the elastic seal member. The shape memory alloy element is configured for applying pressure to the coil spring to thereby augment the compressive force.
